Many people use the heat pump as an air cooler. One of them is Kjersti Kværne. She has a dark house located on a bedrock and actually bought a heat pump to get air conditioning. – I use it when it gets too hot. – Do you think anything about the price of electricity? – No I do not do that. Kjersti Kvaerne bought a heat pump to cool the temperature in the house on hot days.

Comfort is important when deciding how to use the heat pump, says Øivind Tønnesen in Re varmeteknikk AS.

Tønnesen says that modern heat pumps use between half and one kilowatt per hour when it cools down a room. If you have the pump on for ten hours in one day, you use between 5 and 10 kilowatt hours. With the record expensive electricity this week, you then land between 20 and 40 kroner per day in southern Norway. With power support, it will cost between 7 and 14 kroner every day. Tønnesen also says that the price will vary greatly. The heat pump’s capacity and age, the house’s insulation and windows, together with the price of electricity, will make it difficult to say anything exactly. Withstands more elsewhere If you use the heat pump a lot in the summer, it will still make a lot of money. Never turn the heat pump on «auto», advises Professor Trygve M. Eikevik at NTNU – Norwegian University of Science and Technology. Photo: NTNU Professor at NTNU – Norwegian University of Science and Technology, Trygve M. Eikevik, has looked a bit at the use of heat pumps. He says that in other parts of the world, air cooling is only used when the temperature drops to 27-28 degrees. Eikevik advises people to have a conscious relationship with it. – Maybe people should rather ventilate a little more when it is hot, he says. At the same time, he emphasizes that you must never use the heat pump with the window open. Never use auto The worst of all is to have the heat pump on auto. Then you could almost as easily fire with a panel stove, the professor believes. The heat pump will work fine in the winter, until you fire in the fireplace. Then we it start to cool down the house. Spring, summer and autumn you have days where the sun does the job. If the heat pump is allowed to run automatically all year round, I think you will use up again what you have saved on heating with the heat pump, he says. Eikevik’s advice is therefore to follow. – Be aware of the use. Set it to “Heat” when you need heating, and to “Cool” when you need cooling, and never to “Auto”.
